Connect ONE or TWO Door Phones
to your Ordinary Single Telephone Line
Please Note : These Door Station Controllers are for use with ANY One or Two of the range of National Communications Door Phones, which are described on separate pages.
These DOOR STATION controllers are designed to operate with your ordinary (residential type) PSTN telephone line. They are also suitable for sites that do not use a telephone line, such as VOIP users or households that only use Mobile Phones.
ONE or TWO of our range of surface mount or flush mount DOOR PHONES can be connected direct to the DOOR STATION controller. The door phones can be up to 300 metres from the door station controller (the total distance of 1 or 2 door phones).
When a visitor presses the call button on the door phone, our door station controller will RING all the TELEPHONES on your line with a different ring so that you will know the call is from the door phone. All you need to do is to answer any telephone to achieve loud and clear communication with your visitor. There are no call charges.
If you are already on a telephone call, the DS controller will alert you with a call advise tone every 15 seconds. You can then place your telephone call ON HOLD and speak to your visitor by pressing ##. You can then return to your telephone caller when ready by pressing ## again. Similarly, if you are on a door phone call when an incoming telephone call is present the same procedure applies.
Model DS2 incorporates an internal relay which can be used to open or release a door or gate lock. Lock release time is fully programmable.
Models DS3 and DS6 provide two internal relays which can be used to open locks in two separate areas (eg; one at your front gate and one at your front door). The second relay in both these models can alternatively be used to SWITCH ON a light, a video camera/recorder or any other electrical device as soon as the call button is pressed on the door phone and then SWITCH THEM OFF after the call is complete.
Model DS6 has the ability to DIAL OUT to your mobile phone (or any other programmed telephone number) when you are not home and connect you to your visitor at the door phone (normal call charges apply). You will then be able to converse with your visitor and even let them in if you wish.
If you have a SECURITY ALARM or HOME AUTOMATION system, you can use the second relay of model DS3 or DS6 to interface to it and with suitable equipment you can even have a photo or streaming video of your visitors sent to your smart phone.
An Alarm Interface Module (AIM) accessory is also available to automatically set your DS6 to attended or unattended call mode. See page 14 for further details.

Installation Details and Diagram for Sites that Use Only One Telephone Socket
(Including Codless Phone Base Stations with Multiple Handsets)
If you are using just ONE telephone Socket at your site, which is now common for users of Cordless Phones (with 1 or more handsets). then Installation is considerably easier. If you are not planning to use an Electric Lock on a Door or Gate, then you may find that you can install our solution without additional technical assistance.
In the diagram below, you can see that you can connect your Door Station Controller (normally a DS1 if No Locks are required) to ANY Telephone Soicket on your line, by simply plugging it in with the supplied telephone cable.
The only difficult part of this installation is that a cable must be run out to the Door Phone you plan to use, which can be up to 300m away.
Although you only need 4 wires, we recommend CAT5 cable (8 wire cable) due to its low cost and lower resistivity. If the cable will be placed in the ground, then you must use gel filled external CAT5 cable, together with a water proof conduit to carry it within.
A break out box with a short lead is supplied to allow for easy connection of the Cat5 cable to the DS Controller. Note : You can alternatively connect the Cat5 cable direct to the DS Controller (bypassing the connection box) if the cable you are using has an RJ45 Connector. At the Door Phone end, a 4 position connector (with screw terminals) is supplied to connect to the Door Phone.
The centre 2 wires of the RJ45 plug (known as wires 4 & 5 ; note the colour pattern), must connect to the centre 2 pins of the 4 way plug that connects to the Door Phone (polarity does not matter). If you use the supplied Connector box then the wires that connect to the Red and Green cables in the Connector box must must connect to the centre 2 pins of the 4 way plug that connects to the Door Phone (polarity does not matter).
The next 2 wires out from the Centre pair (known as wires 3 & 6 ; note the colour pattern), must connect to the outer 2 pins of the 4 way plug that connect to the Door Phone (polarity does not matter). If you use the supplied Connector box then the wires that connect to the Black and Yellow cables in the Connector box must must connect to the outside 2 pins of the 4 way plug that connects to the Door Phone (polarity does not matter).

Optional Accessories :
Intelligent Touch Tone controlled Relays for Access Control
Our LCU lock control units are intelligent programmable devices with either 1 or 2 internal dry relay contacts, which can be used to control an external device or provide for access or lock control. They are designed to connect to the telephone line in parallel, at any point and you can fit multiple units to a single line. Codes can be any 1 to 4 digit number and the relay can close from 1 to 99 seconds when the code is detected
Model LCU-1 - provides for control of 1 dry relay contact.
Model LCU-2 - provides for independent control of 2 dry relay contacts
Alarm Interface Module
Our inexpensive AIM alarm interface module accessory is designed to operate with our model DS6 door station controller and any security alarm system that provides a set of external contacts that close or open whenever the alarm is enabled or disabled. DS6 has the ability to DIAL OUT and connect a visitor that has pressed the call button on any of our door phones to a pre-programmed telephone number (usually a mobile telephone) if the site is unattended. By incorporating the AIM accessory with the alarm panel, DS6 can be instructed to DIAL OUT IMMEDIATELY whenever the alarm is enabled and to RING internally when the alarm is disabled.
It is important that you fit a high quality ADSL filter ahead of your door station controller unit (and security alarm if used). There are 2 models that we recommend :
Model C10-1 ADSL Filter Splitter
Suitable for sites with up to 3 telephone devices connected to the line.
Model C10-2 Central Style ADSL Filter Splitter
Recommended for sites with 4 or MORE telephone devices connected to the line, or where a security alarm system is used.
